Objective: This meta-analysis aims to assess the efficacy and safety of adding pegylated interferon (Peg-IFN) to long-term nucleos(t)ide analogs (NAs) treatment for achieving functional cure in patients with chronic hepatitis B (CHB). Methods: This meta-analysis was registered in PROSPERO (CRD42024519116). We searched PubMed, Embase, Cochrane Library and Web of Science for randomized controlled trials that compared adding Peg-IFN to long-term NAs with NAs alone for the treatment of CHB. Relative risks (RR) and 95% confidence interval (CI) were pooled using a random-effects model. Results: Seven trials with 692 participants were included. Compared to NAs monotherapy, sequential combination therapy significantly increased the HBsAg seroclearance rate (RR 4.37, 95%CI: 1.92–9.55; I2 = 0%) and HBsAg seroconversion rate (RR 3.98, 95%CI: 1.50–10.54; I2 = 0%), and the results reached statistical significance. Compared to NAs monotherapy, sequential combination therapy showed a significant increase in HBeAg seroclearance rate (RR 2.04; 95%CI: 0.47–8.82; I2 = 73%) and HBeAg seroconversion rate (RR 2.10; 95%CI: 0.41–10.71; I2 = 67%), but did not reach statistical significance. Sequential combination therapy was more likely to experience adverse events. Although most reactions are mild and reversible, vigilant monitoring for treatment-related adverse events is essential, with prompt intervention when needed. Conclusion: For CHB patients on long-term NAs treatment, sequential combination therapy boosts HBsAg seroclearance and HBsAg seroconversion rates compared to monotherapy. However, it may increase adverse events. Additional studies are needed to thoroughly evaluate its clinical effectiveness, given the current limited research available.

Objective: Nondisplaced femoral neck fractures constitute a substantial portion of these injuries. The optimal treatment strategy between internal fixation (IF) and hemiarthroplasty (HA) remains debated, particularly concerning cost-effectiveness., Methods: We conducted a cost-effectiveness analysis using a Markov decision model to compare HA and IF in treating nondisplaced femoral neck fractures in elderly patients in China. The analysis was performed from a payer perspective with a 5-year time horizon. Costs were measured in 2020 USD, and effectiveness was measured in quality-adjusted life-years (QALYs). Sensitivity analyses, including one-way and probabilistic analyses, were conducted to assess the robustness of the results. The willingness-to-pay threshold for incremental cost-effectiveness ratio (ICER) was set at $11,083/QALY following the Chinese gross domestic product in 2020., Results: HA demonstrated higher cumulative QALYs (2.94) compared to IF (2.75) but at a higher total cost ($13,324 vs. $12,167), resulting in an ICER of $6,128.52/QALY. The one-way sensitivity analysis identified the costs of HA and IF as the most influential factors. Probabilistic sensitivity analysis indicated that HA was more effective in 69.3% of simulations, with an ICER below the willingness-to-pay threshold of $11,083 in 58.8% of simulations., Conclusions: HA is a cost-effective alternative to IF for treating nondisplaced femoral neck fractures in elderly patients in mainland China., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Wang, Tan and Sheng.)

Objectives: Anterior cruciate ligament injury is the most common type of knee joint ligament injury. Anterior cruciate ligament reconstruction has a high failure rate, with bone tunnel abnormalities as the most significant factor in these failures. Digital orthopedic technology can effectively develop implementation plans for the revision, thus increasing the success rate. This study aims to develop a surgical plan for anterior cruciate ligament revision by employing multiplanar reconstruction (MPR) for measuring bone tunnel position and diameter, and simulating bone tunnel creation via 3D printing preoperatively., Methods: A total of 12 patients who underwent anterior cruciate ligament revision at the Third Xiangya Hospital of Central South University between 2014 and 2021 were retrospectively studied. The data included patient demographics, preoperative formulated knee joint 3D printing models, and preoperative knee CT scans. The study measured the bone tunnel's diameter and position to guide the establishment of revision bone tunnels during surgery, reassessed the postoperative bone tunnels, and evaluated knee joint functional scores [including International Knee Documentation Committee Knee Evaluation Form (IKDC) score, Lysholm score, and Tegner exercise level score]., Results: Preoperative measurements revealed suboptimal femoral tunnels positions in 4 patients and tibial tunnels positions in 2 patients. MPR and 3D printing technology were used to guide the establishment of a new bone canal during surgery, and postoperative measurements were satisfactory for all patients. Preoperative measurements demonstrated the interclass correlation coefficient for femoral tunnels and tibial tunnels diameters were 0.843 ( P <0.05) and 0.889 ( P <0.001), respectively. Meanwhile, the intraclass correlation coefficient were 0.811 ( P <0.05) and 0.784 ( P <0.05), respectively. The intraoperative diameter of femoral and tibial tunnels showed excellent correlation with postoperative CT measurements, with intraclass correlation coefficient values of 0.995 ( P <0.001) and 0.987 ( P <0.001), respectively. All bone tunnel positions were within the normal range. At the final follow-up, knee joint function scores in all 12 patients improved significantly compared to pre-surgery ( P <0.001), and the reoperation rate was zero., Conclusions: MPR and 3D printing technology can accurately measure the parameters of reconstructed anterior cruciate ligament bone tunnels. Personalized revision plans for patients with reconstruction failure enhances the success rate of revision surgery and improves patient prognosis.
